Annealing Process
Process
- Preheat oven to 80-100°C
- Place print in heat-resistant container
- Heat for 1-2 hours
- Cool slowly (avoid rapid cooling)
Effects
- • Heat resistance improves to over 100°C
- • Crystallization progresses, strength improves
- • Dimensions shrink slightly (about 2-3%)
Use Cases
Suitable Applications
- • Heat-resistant parts
- • Automotive interior
- • Tableware & cutlery
- • High-temperature parts
Pros & Cons
Pros: High heat resistance (after annealing), easy printing, food-safe
Cons: Annealing required, significant shrinkage, expensive
Precautions
• Annealing (heat treatment) is required. Heat in oven at 80-110°C for 1-2 hours.
• Shrinks about 10-15% during annealing; consider dimensions in design.
• Heat resistance similar to standard PLA before annealing.
